2Mx36 synchronous SRAM, 0.45 ns access
The R1QDA7236ABB-19IB0 is a high-speed synchronous SRAM from Renesas Electronics, organized 2Mx36 with a 0.45 ns access time — this places it in the class of parts used for / cache buffers, network packet memory, or high-speed data acquisition front-ends where the bus cycle time is the bottleneck. The 36-bit word width (2M depth) maps cleanly to a 32-bit data bus plus parity or ECC lane without external muxing — a common requirement in telecom line cards and RAID controllers.
Active production, bulk packaging
Supplied in Bulk (tray or tube), not tape-and-reel. For high-volume pick-and-place, confirm the feeder compatibility or plan a tube-to-reel transfer at the CM.
